INVERTED INCANDESCENT GAS-LIGHT.

To all whom it may concern Be it known that I, VIe'ron H. SLINAcK, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Inverted Incandescent Gas-Lights, off which the following is a specification.

The principal object of the present invention is to prevent breakage of the fragile elements, more especially the mantles, such as is due to shocks, are and vibrations, and to provide for keeping the mantles in substantial co-aXial relation with the downwardly discharging burner mouth.

Other objects of the invention are to provide a comparatively simple, efficient and inexpensive combination of mechanical means or elements for accomplishing the ob j ects or results stated.

Generally speaking the invention comprises the combination of an inverted Bunsen tube having a downwardly discharging burner mouth, an inverted mantle, a spring arm, and a carrier hanging from the arm and provided with means for limiting its swinging motion and adapted to yieldingly support the mantle in inverted position beneath the burner mouth in substantial coaxial relation therewith.

The invention will be claimed at the end hereof, but the particular embodiment of it chosen for illustration in the accompanying drawings will be first described, and in those drawings, Figure 1, is a side elevational view, partly in section, of a street light burner embodying features of the invention. Fig. 2, is a top plan view of the same, and Fig. 8, is a sectional view, taken on the line 8 3 of Fig. 1.

In the drawings 5 is an inverted Bunsen tube having a downwardly discharging burner tube 3.

8, is an inverted mantle and 17 is a shade. The mantle and the shade are fragile, more especially however the mantle.

10 is a spring arm consisting in the pres ent instance of a leaf C-spring. One end of this arm 10 is attached to the Bunsen tube 5 and the other end is free. From the free end of the spring 10 the mantle 8 is suspended as is also the shade 17. When the shade 17 is thus suspended its weight,

together with the weight of the parts that carry it, are sufiicicnt to promote the proper absorption by the spring 10 of shocks. jars and vibrations imparted to the gas pipe 1 as by passing trailic where the invention is applied to street lamps, or as by other causes where the invention is applied to inverted lights that are employed in buildings, mills and other places subject to vibrations, shocks and jars. As shown the spring 10 is pro vided with an upwardly projecting point 11 arranged co-axially with the discharge open ing of the burner 3 or substantially so.

Seated upon this point 11 so as to be free to swing thereon is a socket or concavity formed in a carrier from which depends the mantle 8 and the shade 17, but the swinging movement of the mantle and shade is confined within certain limits by a stop cooperating with the depending end of the Bunsen tube. As shown the carrier eomprises a squirrel cage structure 12, having in the present instance, three arms and the stop comprises the ring 18 that forms the lower end of the squirrel-cage structure and is of somewhat larger diameter than the depending end of the Bunsen tube which it encircles.

13, is a cap depending from the squirrel cage structure and to it is detachably connected, as by means of a bayonet joint or the like, a shade ring 1st having pinch screws 16 for holding the shade 17. The mantle 8 is suspended from the ring 14: by means of a spider 15 upon which the arms of the mantle rest. It may be remarked that the parts which constitute the carrier are concentric with the socket or concavity so that the carrier hangs vertically from the point 11. Since the pin 11 is alined with the center of the burner mouth it follows that the mantle 8 is suspended and maintained substantially co-axially with the burner tube; the stop 18 operating to prevent any undue or undesirable swinging motion but not preventing freedom of action of the spring 10. The weight of the carrier to- .gether with the weight of the shade, when it is suspended in the manner described, affords suflicient inertia which the mantle alone might not afford for permitting the spring 10 to properly absorb shocks and vibrations. Otherwise stated the spring 10 is normally under slight compression suchas adapts it to absorb and take up shocks, jars and vibrations.

So that the drawing may be understood in detail it may be said that 6 is a by-pass for flooding the upper end of the Bunsen tube when the light is lighted.

2, is a valve, a is a pressure regulator and 7 is a climbing lighter.

It will be obvious to those skilled in the art that modifications may be made in details of construction and arrangement with out departing from the spirit of the inven tion, hence the invention is not limited to such matters or otherwise than the prior state of the art may require, but

hat I claim is:

1. In an inverted incandescent gas light the combination of a Bunsen tube having a downwardly opening burner mouth, a spring arm provided with a point disposed concentrically with and above the burner mouth, a carrier having a socket for the reception of the point from which it depends substantially co-axially with the burner mouth, a mantle depending from the carrier, and a stop for the carrier, substantially as described.

2. In an inverted incandescent gas light the combination of a downwardly depending burner tube, a spring provided with an upwardly extending point, a carrier provided with a socket for the reception of the point from which it is suspended and with a ring loosely encircling the tube and adapted to operate as a limit stop, and fragile parts nspended from the carrier substantially concentrically with the burner tube, substantially as described.

3. In an inverted incandescent gas light the combination of a tube having a bend and providing a depending burner tube, a carrier encircling the burner tube and terminating above its end and free therefrom, a mantle depending below the carrier, a spring support above the bend, and a detachable pivotal connection by which the carrier is suspended from the spring.

a. In an inverted incandescent gas lightthe combination of a- Bunsen tube having a downwardly extending burner tube, a mantle, a carrier encircling the burner tube and from which the mantle depends, and a spring arm above the Bunsen tube and protected thereby from heat and from the free end of which the carrier depends co-aXially with the burner tube.

In an inverted incandescent light the combination of a Bunsen tube having a downwardly extending burner tube, a carrier having a depending mantle, a spring support, and a pivotal point and socket de tachable connection for depending the carrier from the spring support.

In testimony whereof I have hereunto signed my name.
